Have you ever hard of the brand or manufacturer Criterion?  A few days ago I bought a Criterion radio.  It is a low-boy console with  7-tube TRF chassis.  I already have it playing. 

Sombody is on E-Bay now trying to sell a page from a 1930 Blish, Mize & Silliman Hardware Co. catalog showng Criterion radios.  The two models shown on that page use screen grid tubes, so they are probably one model year newer than the radio I have.  They may not even be from the same maker.  However, the chassis in my radio is painted, and I see that a radio in that ad has a chassis finished in "gold moire," which would mean paint.
